The Great Debate UK
from Environment Forum:
One pesky aspect of climate change is that rising temperatures and stronger storms may increase invasions of non-native species to places that have no natural defenses against them.
The issue is mostly being ignored at the annual U.N. climate talks in Cancun, Mexico, California's Agriculture Secretary A.G. Kawamura said.
Just a few miles away from the talks an island called Isla Mujeres has been fighting an infestation of cactus moth swept there during a hurricane, storms that are expected to get stronger as a result of climate change. The moth destroys prickly pears, and if it makes it to mainland --ferries full of tourists go to and fro Cancun to the island all day long -- it would could harm more than the price of prickly pear fruit for your margarita.
Mexico is afraid it could reach the Chihuahuan and Sonoran deserts and hurt the 76 types of pricklies there and the 38 found only in Mexico. Many insects eat only the cacti and in turn many desert birds and mammals depend on those insects.
