There are approximately 2,000 million hectares of tropical forests in the world. Deforestation is happening all over the world, even in Canada. We may not notice it, but it's still here.

Many hectares are constantly being converted to other land uses, mostly for agricultural uses. Several types of deforestation occur from "slash and burn" farmers, commercial farmers, ranchers, loggers, firewood collectors, industrial developers and much more.

Forests are very important to the environment because they use carbon dioxide (CO2) and produce oxygen. They also provide food and a home for many different types of plants and animals. For example, if there was deforestation in a certain area where many wolves live, they would be driven out of their home and be forced to live in a different habitat. That could cause the animals in the tropic level below them to die because there are more top carnivores now.

Cutting down trees is called "deforestation" and it can have serious effects.

If animals' homes, which are built in and around the trees, are destroyed, many species will become extinct and it would be a great loss. For example, several species became extinct from deforestation before the scientists could even study them.

Deforestation also affects the climate. When rain falls on a forest, new clouds are created. If huge areas of trees are cut down, clouds do not form, rain does not fall and the land becomes drier. The CO2 builds up and adds to the global warming which is making the Earth become hotter.

The reproduction of the trees is much slower than the cutting of them. Many trees were planted to replace woodland and to create forests but it has decreased the biodiversity of the plant and animal life since the plants that were planted were mostly all the...
