Sustainable forest management involves the maintenance and enhancement of forest environments, ensuring longevity of forest ecosystems while allowing the best possible environmental, economic, social and cultural opportunities now and into the future. In Canada, the world’s largest exporter of forest products, harvest rates and strict jurisdictions are set to ensure long term ecosystem sustainability, protecting soil and water resources and 55% of all energy used by the forestry sector is renewable bio-energy.

Gentoo Penguins lay a couple of eggs but if food is in short supply once the eggs have hatched, one chick is often sacrificed in order to feed the stronger of the two.

The forests on the Indonesian island of Sumatra are witnessing some of the fastest rates of deforestation in the world. Over the last decade, dozens of pulp and paper companies have established themselves on the island chopping down trees and setting up palm oil plantations on the cleared land. These changes have far-reaching environmental as well as socio-economic impacts on the island communities that are so dependent on the natural resources and ecosystem services provided by the rainforests.

Black Carbon (BC), also known as soot, is produced through the incomplete combustion of fossil fuels and biomaterials. Apart from its negative health impacts, BC also has significant climate effects because it generally has a lower albedo than its surroundings, which increases the amount of radiation absorbed both when BC is present in the atmosphere and when it is deposited on land (Stjern et al. 2017). Due to the large albedo differences, the effects of BC are especially significant in areas that are normally covered in snow or ice (Hadley and Kirchstetter 2012; Sand et al. 2016; Kang et al. 2020).

Norilsk is located between the West Siberian Plain and Central Siberian Plateau at the foot of the 1,700-meter high Putoran Mountains, on some of the largest nickel deposits on Earth. Consequently, mining and smelting ore are the major industries.

Methane is a highly potent greenhouse gas and its reduction is given ever greater priority in international emission reduction policies (see, for example, https://www.globalmethanepledge.org/). There are several suggested ways to remove atmospheric methane (see Nisbet Jones et al. 2021; and Ming et al. 2022; see in this report also iron salt aerosols and zeolites). One of the main issues with methane removal is that atmospheric methane concentrations are very low. This means that very large volumes of air, and related energy demands, are required, making the use of ventilators like those used for DACCS (see direct air capture) more complicated (Nisbet-Jones et al. 2021).

Methane is a highly potent greenhouse gas and its reduction is given ever greater priority in international emission reduction policies (see for example https://www.globalmethanepledge.org/). There are many different materials that have been suggested and explored to capture methane (Alonso et al. 2017).

South the shores of the islands outside Arendal a marine national park is in planning. The rolling stones, remains from the last ice edge is a main feature of the protection plans. The recreational value is immense. It should become a win-win for tourism and conservation.
