Education, education, education. Also healthcare, and access to contraception. I don't have any references available, I'm afraid, but repeatedly we have seen that when standards of education are improved in a community - especially education of women - birth rates go down. When child mortality goes down, so does fertility, but that has little effect on ...

Would levying taxes on non-organic meat be an effective means to reduce consumption and thus reduce the environmental harm? Yes. But. It would add complexity compared to just taxing all meat, and thus make the tax less efficient. The increased costs would be the primary cause of reduced consumption. Whether only taxing conventional meat would have a ...

I'll split this answer into two parts: the political and the personal Political impact Whatever political system you live in, you have some route to make a political impact. The amount of impact will depend on your exact circumstance, but you will have some impact somewhere: through your elected representative, through a national political party, through a ...

It may sound contradictory, but according to scientist and statistician Hans Rosling, the main criterion to limit population growth is a reduction of the child mortality rate (see also his Ted Talk on the topic and the stats below). Child mortality rate vs Country population growth rate (including migration) in 2011, Each bubble is a country, bubble color ...

It has already been stated that population growth decreases in countries that experience an increase in prosperity. It seems clear to me that this goes hand-in-hand with access to education for all members of the population. To encourage a decrease in number of births per woman in the developing countries, it would seem that the primary goal would be to keep ...

Fight to poverty. In fact this is the main goal of the UN agency for sustainable development. People living in poor countries use to have more children because they need somebody to take care of them when they'll be old and they rely on their family and cluster to help eachother. It's too easy to thingk that they don't do contraception because of their ...

Each offset program is problematic in its own way. We can't (feasibly) put carbon back; we can only try to store away what's already out there, or give more people more options to develop without hydrocarbons. Consider giving to organizations that protect forests and other natural areas to preserve existing trees through policy action or by buying land, ...

On first thought I was tempted to say yes, because you are creating a longer-living carbon sink for part of the wood (compared to letting the tree die naturally). But on second consideration: Look at the amount of material that gets discarded when making wooden objects. I estimate that's easily 70% of the tree: 30% in the construction phase alone, plus ...

Increase broadcast coverage of television soap operas From the abstract of a research paper titled "Soap Operas and Fertility: Evidence from Brazil" (pdf): We estimate the effect of television on fertility in Brazil, where soap operas portray small families. We exploit differences in the timing of entry into different markets of Globo, the main novela ...

What those countries has in common are non-existant infrastructure like banking system, electricity and sewage. So comfort in everyday life is not there. A good car delivers instant gratification. It is more affordable than a house, has air conditioning and temporary isolation from the atmosphere. A terrible long term solution, but a great one for the ...

I don't know about CCS, sequestration never seems to get close to scaling up for a reasonable cost. (A flagship “clean coal” plant is a flailing mess.) Carbon-capture, however, might have a new price ceiling set: CBC.ca: carbon from air to fuel, but also Vox.com: Sucking carbon out of the air won’t solve climate change, but it might fill in a few key pieces ...

People world-wide like status. I return to the South Pacific I take WalMart bags from America. The ladies love to go to town with them. It means someone in our family is rich enough to go there or our friend can go there. Same with the big cell phone. A vehicle says I can out run you, ford deeper rivers and climb up the side of a mountain faster to get away ...

Even though I agree with most of the previous answers that education and economic equality would be the most efficient mechanics in the long-run, I feel like they do not directly answer your question as it seemed you wanted to have an instrumental answer in the style of IF-THEN. Given the fact that a multidimensional problem such as over-population ...
