My main comment about this is the focus solely on technology development. While this is important, there is no disputing humans’ availability to create new technologies; that is the easy part. And also, let’s not forget that our planet does not need our help in replenishing itself.
it is imperative that we look at the root causes of the problems. So instead of capturing CO2, we need to look at what produces the C02 emissions.
If we break down the emissions by economic sectors, you will notice that Agriculture, Forestry and Land use represent 18.4% - 24% of global emissions.
I talk about agriculture because this factor can be addressed with social-economic inclusion instead of technology development.
Allow me to elaborate,
As an example, the price of green coffee has remained in a downward trend since the International Coffee Organisation (ICO) member countries’ inability to sign the international coffee agreement in 1983.
Despite revenues for roasters and retailers have increased over the past two decades, the volatile nature of commodities prices, green coffee production surplus, and lack of information on the real full cost of production means that many farmers in coffee-producing countries struggle to cover their production costs and as a consequence their ability to increase their living standard.
To cope with these challenges, farmers have been forced to increase their productivity and efficiency. For this, coffee farmers clean large parts of the rainforest to increase their production.
An extensive review of published data on coffee land-use change suggests that apart from Brazil, where increases in production are driven by technology, in nearly all countries where coffee production is expanding rapidly, deforestation is the primary source of new coffee lands.
The data shows that there is a correlation between falling coffee prices and deforestation due to coffee production.
In summary, this cycle goes like this: Falling coffee prices- increase poverty-need to increase production-deforestation-Co2 emissions.
That is why I suggest focusing less on technology development and addressing the social-economic discussion on sustainability.
