Bio diversity is the variety of life in the world or in a particular habitat or ecosystem. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
Cons- A big con is deforestation. Humans come in and cut down up to 80% of the forests. A solution being made is reforestation where people come in and plant new trees. Another con is air pollution. The main cause of the is industrial factories. People are now trying to locate factories further away from forests.
Pros- One thing people do to conserve our temperate deciduous forests is making national parks to preserve them. Many people are trying to make more of these parks to preserve more land.
