Plants don't cause weathering. They can't round out a rock or create a smooth side.
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Indeed, global warming has been in the foreground of politics and science for quite some time. There have been numerous studies conducted on the effects of global warming and what we might do to mitigate any threats. I think some policymakers are wary of the findings and some can trust that the conclusions are sound for the following reason.
Politicians are wary because, in reality, there are no 100% conclusive arguments that confirm that global warming is the result of humans. For other politicians, the evidence provided by environmental institutions is valid and they are prompt to proclaim that humans are to blame for global warming.
What is real, is that earth scientists think that global warming caused significant climate change in the past. And when they say the past, they mean a time before humans appeared on planet earth.
Climate change or global warming is not new for planet earth. It is a phenomenon that has happened in the past according to scientists and national agencies. It is believed that global warming had caused natural disasters such as the melting of ice caps and the flooding of many lands on Earth, destroying life forms.
That is why right now, many agencies are closely researching climate change. Among those institutions are the US National Academy of Sciences, the Geological Society of America, the American Meteorological Society, and the National Aeronautics and Space Administration.
Basically, without this movement, people would not have come to America (before 15th century and 11 Century in the north where the Vikings came) and they would not have established the cultures and developed the languages which are still practiced and spoken today (such as the Maya culture/language and the Quechua culture/language).
Decreased risk of injury, increased bone density and strength and reduced osteoporosis
Well, in the case of mortality, this could be true. I say this because developed countries have better technology. This technology can be used in the hospitals to treat the sick. However, in developing countries, there is not much technology available for all these, so people may die of curable illnesses. Hope i helped.
