Hypothesis: How do chemicals such as pesticide use correlate to pollinator decline in addition to global warming and how does it contribute to plants reproducing? I believe it is absolutely deadly.In that all of these detrimental factors contribute synergistically making the damage to all pollinators significantly greater. Pollinators are very sensitive to temperature.And if it's even a few degrees off pollinators can die. Now that it is warmer all over the planet, it causes plans to bloom earlier. A lot of wild plants need a pollinator just to reproduce, which in turn speeds up the decline of both the plants and pollinators. The plants decline then causes less food for animals and humans raising 02 levels. Point blank pesticides kill pollinators ability to retain memory g p s location and where to find pollen.
