For the one billion poor people who depend on products from the seas and rivers as their main food source, the result is malnutrition and hunger. Reversing the trend towards global warming. The problem Most scientists now agree that temperatures around the world are on the rise, creating an immediate and dangerous problem. The more people there are, the more oil, coal, natural gas and wood we burn, throwing gases into the air that are heating up our planet. These gases can create catastrophic effects on our climate including more severe droughts, more intense rainstorms and rising coastal water levels.
Deforestation contributes to global warming as well.
Preserving the precious variety of plant and animal species on our planet. The cutting down of tropical forests threatens the homes of thousands of plant and animal species that are near extinct. Because of human encroachment on the habitats of other species, we could easily lose half of all living species a mass extinction on a scale comparable to those that ended past geologic eras. This would mean the irretrievable loss of plants that fuel our medical advances. We could also lose vital ecosystems and find our human food supplies severely threatened.
