In addition, fish began to die in some of the lakes in the region. What could have caused these deaths to occur simultaneously in two very different habitats?

Which of these hypotheses does not explain why increased CO2 levels in the atmosphere could cause a decrease in the productivity of some crops because of changes in climate?   A) There could be increases in average winter temperatures that reduce the growth of crops. B) There could be decreases in precipitation in some regions that reduce growth in some crops. C) There could be shifts in the ranges of some important species in the community, such as pollinators, that cause reduction of growth in some crops.
In the past, sometimes Aboriginal Albertans would purposely set prairie fires in the spring in a type of "controlled burn" in order to begin a secondary succession. Explain 1.) why this was done, and why this practice is no longer done. One of the first species to colonize burned forest is fireweed, a plant that makes a tall stalk of fushia-coloured flowers. Conduct an Internet search to find at least two 2.) traditional uses of this plant by Aboriginal peoples.
Why is the redevelopment of lost forestland so essential to combat the effects of global warming?
