Pine cones have a few adaptations, depending on the species. Some do exactly as you describe: open and close with changes in air moisture. The tissues of the individual cone scales differentially absorb water from the atmosphere on the top and bot.

In January, the mayor of London announced that 7, trees would be planted before the end of the following year.

Jun 03, Trees also store carbon dioxide in their fibers helping to clean the air and reduce the negative effects that this CO2 could have had on our environment. According to the Arbor Day Foundation, in one year a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange.

May 04, Some trees are markedly more effective at filtering pollutants from the air than others. To make the most difference in air quality in a street or city, it has to be the right tree for the job. Time required to dry pine is subjective to air flow and humidity.

In a moist climate, green pine can take up to a year to dry to 19 percent. If you're drying milled pine for furniture, trim work or cabinets, the time required to bring it down to 12 percent can be as little as a few days or as long as a few weeks or more.
