Fertilizer can pollute a wetlands ecosytem because the fertilizer has toxins in it so the animals will die and there will be no more animals to make a wetlands ecosytem because toxins have bad chemicals in them.
well from what i know is that with all the extra carbon we emit into the air, we intoxicate the organisms and they bring these poisons back to the wetlands and affect the biome. plus we pollute with garbage these wetlands, and very bad for the biome and the food chains with in them.
The weather in a wetlands is determined by geography and climate. Only larger wetlands have an effect on their environment. As water evaporates from the wetlands, it can create humidity and more frequent rain.
