ANSWER: All of the above
Explanation:
- Among the reasons are — the way farming has changed so there’s not enough diversity and wild flowers for pollinators to use as food; pesticide use, habitat loss to cities; disease, parasites and pathogens; and global warming.
- The variety and multiplicity of threats to pollinators and pollination generate risks to people and livelihoods.
- These risks are largely driven by changes in land cover and agricultural management systems, including pesticide use.
- But these are problems that can be fixed, and unlike global warming, the solutions don't require countries to agree on global action — they can act locally. The solutions offered mostly involve changing the way land and farming is managed.
