Changes in Habitatsby Denise Carroll Let’s Save Our Earth!
Habitat • The place where an animal or plant lives and grows is called its habitat. • A habitat is where and animal finds the food, water, and shelter it needs to live.
How are animal habitats destroyed? Many habitats are destroyed by people or by nature. • Droughts • Floods • Lightning and Forest Fires • Land, Air, or Water Pollution • Storms, Hurricanes, Tornadoes • Trees are cut down to build houses, buildings, roads, furniture, and paper products. THINK: What would happen if an animal’s habitat was destroyed?
Habitats are destroyed by . . . • Droughts are when an area does not get rain for a long time. • The ponds or streams will dry up. • Most pond plants will die. • Many pond animals die or move to other ponds. • Some crops will not grow.
Habitats are destroyed by . . . • Floods are when an area gets a lot of rain for a long time. • Plants and animals get too much water. • Many plants die. • Many animals die or move to drier places.
Habitats are destroyed by . . . • Sometimes lightening strikes a tree in a forest, causing forest fires. • Plants and trees are burned and destroyed. • Some animals die, others may be able to move quickly to safer places. • It takes many years for a forest to grow back.
Pollution • Pollution is waste that harms land, water, or air. • Pollution is harmful to people, animals, the environment, and destroys many habitats. 1. Land Pollution 2. Air Pollution 3. Water Pollution
Habitats are destroyed by . . . • Land pollution effects the land destroying life, the environment, and its habitats. • Trash that people do not put in a trash can is called litter. • Litter kills plants and causes animals to get sick or die. We need land to grow our food.
Habitats are destroyed by . . . • Air pollution effects the air we breathe. • Plants and animals need clean air. • Factories and cars put harmful smoke and fumes in our air. • Air pollution causes major damage to our health and the environment. Forests are nature’s air cleaner. We need forest to help keep the air clean.
Habitats are destroyed by . . . • Water pollution effects the water and marine life. • Water pollution destroys water habitats. • Water pollution has caused animals to become endangered. • All living things need clean water. • Water is nature’s perfect drink! Water is a valuable resource that no one could do without.
Habitats are destroyed by . . . • Storms • Hurricanes • Tornadoes
Habitats are destroyed by . . . People Nature • Pollution • Litter • Construction: new houses, buildings, and roads • Clearing forest to make wood and paper products. • Droughts • Floods • Lightning and Forest Fires • Storms, Hurricanes, Tornadoes
Think:What would happen if an animal’s habitat were destroyed?
Endangered or Extinct? • The number of people in the world is growing at an alarming rate. • But this is not true for all animals. • In some cases, there are only a few of one type of animal left in the wild. These animals are endangered, or at risk of dying out. • If they die out completely, they become extinct.
Why does this happen? There are lots of reasons why animals become endangered or extinct. The most common are: • loss of habitat (forests cut down, rivers drying up). • pollution poison the animals. • hunting (for sport, their fur, tusks or meat).
Caring for the Environment • It is in our own best interests to look after the world we live in. • If a habitat is lost or damaged, it has an effect on everything. • Remember - once something becomes extinct, it’s gone forever!
Think: What can you do to help the environment? Recycle or Reuse • Recycle means to change something so it can be used to make something new. • Reuse means to use something more than once.
Ways People Help the Environment People can take care of their environment and keep it clean. • Plant trees • Recycle or reuse things • Don’t litter • Don’t pollute • Walk or ride a bike • Develop national parks • Learn more about habitats • Making laws to protect habitats • Setting aside land for wildlife
Congratulations! • You are on your way to building a safe and healthy environment for us to live.
