FIGHT FOR YOUR WORLD
Global warming
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 ̊C (1.4 ̊F), with about two-thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation. These findings are recognized by the national science academies of all major industrialized nationsEffects significant to humans include the threat to food security from decreasing crop yields and the loss of habitat from inundation

WHAT ELEPHANT EAT
Elephants
eat grasses, leaves, bamboo, bark, roots. Elephants are also known to eat crops
like banana and sugarcane which are grown by farmers. Adult elephants eat 300
400 lbs of food per day.
Elephants
form deep family bonds and live in tight matriarchal family groups of related
females called a herd, Elephants are extremely intelligent animals and have
memories that span many years, Because of their large size, elephants have a
huge impact on their environments and are considered keystone species. Their habit
of uprooting trees and undergrowth can transform savannah into grasslands. When
they did for water during drought, they create waterholes that can be used by
other animals
Elephants
are large mammals of the family Elephantidae and the order Proboscidea. Traditionally,
two species are recognised, the African elephant (Loxodonta Africana) and the
Asian elephant (Elephas maximus), although some evidence suggests that African
bush elephants and African forest elephants are separate species
