Scientific outlook
Possible future in 50 year:
The energy price keept dropping and renewable energy became more efficient and available.
Most of the fuels are sustainably produced by technical conversion to hydrocarbons, which are available in huge amounts.
The biotechnology and starch based industry is based on a variety of substrates, mainly wastes and glycogen produces from methanol.
The arable land that was previously used to grow energy crops is now renatured or used for food crops. The renaturing of area that was a former part of the bioeconomy, now binds a large amount of CO2 from the atmosphere which brought climate change to a halt.
With the left over arable land and improved agriculture, we are guarantee food security without an extensive use of fetilizers. The decreased use of fertilizers reduced the polluiton of rivers and oceans which lead to a more stable environment.
