Question

1. Why should people who love in cities be concerned about rain forests being destoryed?

2. It is estimated that 100 plants become extince in rain forests each day. How many plants species become extince in rain forests in a year?

Answer 1

spend some time in a rain forrest and you will see for yourself

Answer 2

Most people in cities do not worry about the effects on the rainforest.  But they should because of many reasons.

  Rainforests contribute 70% to the total oxygen supply on the Earth.  No matter where anyone lives, if the rainforest was cut down, there is going to be major effects on everyone.  

2.) I'm not sure about the next question. I do know that only about 1% of the total number of species that ever existed are left in the world. Scientists have estimated that only a very small percentage of this 1% have been discovered and there may be millions of undiscovered plants and animals.  The rainforest is said to have the highest biodiversity.

I don't think that there is an exact number or estimate. It all depends.  Every year a larger number of plants become extinct. There might be more deforestation this year than last year.  But if you needed a number, than it's possible to just multiply 100 by 365 and get 36500 plant species go extinct in a year.

Good luck!!
