Environmental health activities are those which are aimed at:
- reducing the risk (chance) of getting diseases and injuries from the environment
- promoting good health
- a good water supply;
- the correct disposal of (getting rid of) liquid and solid waste
- a healthy food supply
- pest control
- personal hygiene
- a healthy house
- community environmental health education
Water, unlike many other things, cannot be manufactured in a factory. When we lose water, it is gone forever.
Unfortunately, not everyone can just turn on a tap and get fresh, clean water. In fact, one in ten people do not have access to clean drinking water. Sadly, many people get very sick from drinking, bathing in and/or cooking with water that is not safe.
It can be easy to take water for granted, because we can turn on the tap and use our clean drinking water for drinking, cooking, taking a bath, filling a pool and many other things. However, if we do not work hard to conserve our fresh water, we may soon run out of it too.
There are several important things that conservationists do to save water. These are:
- Reducing water waste
- Protecting the clean water we have. If water is polluted by harmful chemicals or garbage, we can’t use it to drink, bathe in or water crops
- Helping water management plants minimize the amount of water they need to use on a daily basis.
- Encouraging companies to make devices that do not use as much water as they did before.
Getting to Know More About Conservationists
While water conservation is perhaps the most important form of conservation, there are other important natural resources that we must protect as well. These includes trees, animals and natural habitats such as jungles, forests, mountains and plains.Before conservationists came along, a lot of nature was destroyed. Hunters hunted down too many wild animals and some of them became extinct or almost became extinct. Too many trees were cut down in some areas and that resulted in certain places turning into desert. In other cases, water was overused, which resulted in some lakes and rivers completely disappearing. Conservationists try to make sure that things like this do not happen again; that way, we can all enjoy a beautiful world full of many animal species and all the different things we need.
There are many different types of conservationists. Some help to protect wild animals. Others try to take care of certain places, such as wetlands (swamps), deserts or forests. Other conservationists are very concerned about water and do their best to make sure that we don’t run out of it. Yet others care for the soil, helping to keep it healthy so that we can grow healthy crops.
Would you like to be a conservationist too? You don’t have to wait until you get older. Here are some things you can do right now to help keep our natural world healthy and happy:
- Converse electricity by turning off the lights when you leave a room. You can also ask your parents to buy energy-saving bulbs that use less electricity than normal ones.
- Throw garbage in the garbage can instead of on the ground
- Recycle bottles, old newspapers and other things. In some cases, you can even earn a bit of extra pocket money by taking these items to a recycling plant!
- Don’t leave the water running when you wash your hands, brush your teeth or take a shower. Turn it off when you are not using it
- Not flushing the toilet when you don’t need to
- Taking short showers
- Using a bucket to wash your bike or your parent’s car instead of leaving the hose running
- Watering the garden in the early morning or the evening, instead of during the day
- Collecting rain water in a bucket. You can’t drink rain water but if the bucket is clean you can use it to fill an outdoor pool to play in in the summer. You can also use rainwater to water your yard or wash a car or bike.
Important Facts about Water
Can I drink water if it looks clean?
The water that comes out of your tap is OK to drink; however, you should not drink water just because it looks clean to you. There are many harmful chemicals in certain types of water that do not make the water look dirty but could make you very sick.Which countries do not have clean drinking water?
The tap water in the United States, Australia, New Zealand, Japan and Canada is safe to drink. In other countries around the world, people either use bottled water or a water purifying machine that purifies the tap water to make it safe to drink (this water comes out of a separate faucet)Can I drink water from the garden hose?
The water coming from the garden hose is the same water that comes into your kitchen faucet; however, you should not drink it. Garden hoses are made using special chemicals, and these chemicals get into the water and make it unsafe to drink.Why is our tap water clean?
Our tap water is clean because water treatment plants add special chemicals to it to make the water safe to drink.Why can’t we use salt water?
There is a lot of salt water in the world; in fact, oceans cover a larger area of the world than land does. Unfortunately, the large amount of salt in ocean water makes it unsuitable for drinking. It not only tastes bad but would also make you very sick. On top of that, salt is bad for plants and soil. Watering plants with salt water would make them die and would also ruin the soil, making it impossible to grow other plants in the same area.Some conservationists are trying to make salt water safe to drink. This can be done by a process called desalination (this means taking the salt out of the sea water so we can use it for drinking, cooking and other things). However, it is very difficult and expensive to desalinate water, so for right now the ocean water cannot help us very much.
Why are we in danger of running out of water?
Everyone needs water and the fact that the world population is growing means that there are more people than ever who need clean drinking water. Additionally, farmers need to grow more food to feed more people, which means they need more water to do so. Ranchers (people who raise cows, pigs, chickens and other animals that we eat) also need more water to feed their animals so that we can all have meat to eat.Sadly, we have not always taken care of the water we have and so have lost a lot of it. When water is lost, it is gone forever. Why? Here is a simple explanation of how the water cycle works.
- The water in the lakes, rivers and ocean evaporates (is dried up by the sun). This water then turns into clouds.
- When it rains, the water comes back to us. It waters the soil and fills the lakes and rivers.
- Then the sun comes out and the water dries up again. The process continues on and on and on.
Water and Soil
It is not just live things like people, plants and animals that need water. The soil (the dirt that we grow food in) also needs water. Plants get their nourishment from the dirt they are planted in; if there is not enough water in the soil; the plants will die.Keeping the soil healthy is an important part of conservation, because without healthy soil we will not have enough food to eat. Conservationists work hard to help the soil get just the right amount of water, as too little or even too much water could ruin it.
- Conservationists plant trees to help protect the soil. If soil gets too much rain, the top part of the soil will wash away. This is called erosion and is bad for the plants, as the top soil is usually softer and has more nutrients than lower layers. Too much erosion creates a desert.
- Many farmers use irrigation to save water when they water their crops. They may also plant rows of trees between certain types of crops to prevent the rainwater from washing the top soil away.
- Some farmers and gardeners use “cover crops” to protect the water in the soil from drying out. What this means is that vegetable crops or even other non-edible plants are planted between rows of crops such as corn. As the name implies, these “cover crops” cover the ground, keeping the moisture in it and thus saving water.
- Ask your parents about planting a garden. Be sure to choose plants that naturally grow in the area, as these are usually best for the soil.
- Do not put too much fertilizer on your garden, as it can ruin the soil.
- Do not over-water your plants. Too much water will wash the soil away. At the same time, make sure your plants get as much water as they need. If the top soil is too dry, the wind will blow it away.
