Barbecues that remove CO2 from the air could play a role in the fight against climate change according to Durwood Zaelke, a leading expert on rapid responses to global warming. This year's outdoor cooking season might be over, but Zaelke suggested at last week's 10:10 talk that from next summer consumers should start demanding barbecues that do their bit for the planet by generating rather than consuming charcoal – or biochar.
We have traditionally used fossil fuels to provide most of our energy needs. These fossil fuels, like gasoline and coal, have some significant disadvantages. First, the world's supply of these nonrenewable resources is diminishing. Second, the prices continue to skyrocket, making it unaffordable for many people. Third, fossil fuels are damaging to the environment. Because of these three reasons, we are beginning to look at alternative energy sources. We really need to look carefully at these sources. Fossil fuels will not be around forever, and we are currently using them as if we have an unlimited supply. This supply, if we continue as we are today, will be gone. Fortunately, there are other options out there, and many of them do not have the same concerns that fossil fuels have, as these alternative sources are environmentally friendly, renewable, and more affordable in some cases.
