Bamboo structures, placards and “lock-ons” are being used to prevent lorries from entering the sites.
The protesters said they planned to stage the protests on Black Friday as the discount day “epitomizes an obsession with overconsumption that is not consistent with a liveable planet.”
Clarissa Carlyon, one of those taking part in the protests in Dartford, South East England, said that action is needed to “address the toxic consumerism that is driving the ecological crisis.”
Carlyon added: “If we don’t talk about what consumerism is doing to our planet and our society then we will not address the planetary emergency that’s happening now.
“We know there is always more to do, and we’ll continue to invent and invest on behalf of our employees, customers, small businesses and communities in the U.K.”
The group said they intend to stay at the sites for at least 48 hours.
“However, we expect the disruption to run into the morning rush hours and we’re asking motorists to take some delays into account,” Essex Police tweeted.
